1. Ni ubuhe buryo bukoreshwa bwahydroxypropyl methylcellulose (HPMC)?
Hydroxypropyl methylcellulose ikoreshwa cyane mubikoresho byubwubatsi, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda. Hydroxypropyl methylcellulose irashobora kugabanywa mubyiciro byubwubatsi, urwego rwibiryo ndetse nicyiciro cya farumasi ukurikije ibisabwa. Kugeza ubu, ibyinshi mubicuruzwa byo murugo ni urwego rwubwubatsi. Mu cyiciro cyubwubatsi, ifu ya putty ikoreshwa mubwinshi, hafi 90% ikoreshwa kubifu ya putty, naho ibindi bikoreshwa mumasima ya sima na kole.
2. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellulose (HPMC), kandi ni irihe tandukaniro mugukoresha?
HPMC irashobora kugabanwa muburyo bwubwoko nubwoko bushyushye. Ibicuruzwa byubwoko bwihuse bikwirakwira vuba iyo bihuye namazi akonje bikabura mumazi. Muri iki gihe, amazi ntagira ubwiza kuko HPMC ikwirakwizwa mumazi gusa nta gushonga nyabyo. Nyuma yiminota igera kuri 2, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bikora colloid ibonerana. Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ibishishwa bizagaragara buhoro buhoro kugeza igihe bibumbiye mu mucyo. Ubwoko bushyushye burashobora gukoreshwa gusa mubifu ya pome na minisiteri. Muri kole yamazi no gusiga irangi, hazabaho guterana ibintu kandi ntibishobora gukoreshwa. Ubwoko bwakanya bufite intera yagutse ya porogaramu. Irashobora gukoreshwa mu ifu yuzuye ifu na minisiteri, hamwe na kole yamazi hamwe n irangi, nta kubuza.
3. Ni ubuhe buryo bwo gusesa hydroxypropyl methylcellulose (HPMC)?
Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mumazi ashyushye, HPMC irashobora gukwirakwizwa kimwe mumazi ashyushye mugihe cyambere, hanyuma igashonga vuba iyo ikonje. Uburyo bubiri busanzwe busobanurwa gutya:
1) Shira amazi asabwa muri kontineri hanyuma uyashyuhe kuri 70 ° C. Hydroxypropyl methylcellulose yongeweho buhoro buhoro buhoro buhoro, mu ikubitiro HPMC ireremba hejuru y’amazi, hanyuma buhoro buhoro ikora ibibyimba, bikonjeshwa bikurura.
2) Ongeramo 1/3 cyangwa 2/3 byamazi asabwa muri kontineri, hanyuma ubishyuhe kugeza kuri 70 ° C, ukurikije uburyo bwa 1), ukwirakwiza HPMC kugirango utegure amazi ashyushye; hanyuma shyiramo amazi asigaye asigaye mumazi ashyushye, imvange yarakonje nyuma yo gukurura.
Uburyo bwo kuvanga ifu: vanga ifu ya HPMC ninshi mubindi bintu byifu yifu, vanga neza na mixer, hanyuma ushyiremo amazi kugirango ushonga, hanyuma HPMC irashobora gushonga muriki gihe nta agglomeration, kuko hariho HPMC nkeya muri buri nguni ntoya Ifu, izahita ishonga mugihe ihuye namazi. —— Ifu yuzuye ifu nabakora minisiteri bakoresha ubu buryo. [Hydroxypropyl methylcellulose (HPMC) ikoreshwa nk'umubyimba mwinshi kandi ugumana amazi muri poro ya poro.]
4. Nigute dushobora gusuzuma ubuziranenge bwa hydroxypropyl methylcellulose (HPMC) byoroshye kandi byihuse?
. Nyamara, ibyinshi mubicuruzwa byiza bifite umweru mwiza.
. Nibyiza, mubisanzwe, nibyiza.
. Iyo hejuru yohereza, nibyiza, byerekana ko harimo kutaboneka neza muri yo. Ubucucike bwa reaction ya vertical muri rusange nibyiza, kandi nibya reaction ya horizontal ni bibi, ariko ntibisobanuye ko ubwiza bwa reaction ya vertical iruta iya reaction ya horizontal, kandi ubwiza bwibicuruzwa bugenwa nibintu byinshi.
(4) Uburemere bwihariye: Ninini nini ya rukuruzi, niko iremereye. Umwihariko ni munini, muri rusange kubera ko ibiri mu itsinda rya hydroxypropyl muri yo ari byinshi, kandi ibikubiye mu itsinda rya hydroxypropyl ni byinshi, gufata amazi ni byiza.
5. Ni ubuhe bwoko bwa hydroxypropyl methylcellulose (HPMC) mu ifu ya putty?
Ingano ya HPMC ikoreshwa mubikorwa bifatika iratandukana bitewe nikirere, ubushyuhe, ubwiza bwa calcium y ivu ryaho, amata yifu yifu n "ubuziranenge busabwa nabakiriya". Muri rusange, hagati ya kg 4 na 5 kg. Kurugero: ibyinshi byifu ya putty i Beijing ni kg 5; ifu ya putty muri Guizhou ni kg 5 mu cyi na 4.5 kg mu gihe cy'itumba; ingano yifu ya putty muri Yunnan ni ntoya, mubisanzwe kg 3 kugeza kg 4, nibindi.
6. Ni ubuhe buryo bukwiye bwa hydroxypropyl methylcellulose (HPMC)?
Ifu ya putty muri rusange irahagije kumafaranga 100.000, kandi ibisabwa kuri minisiteri ni byinshi, kandi 150.000 yuan birakenewe kugirango bikoreshwe byoroshye. Byongeye kandi, umurimo wingenzi wa HPMC nukubika amazi, ugakurikirwa no kubyimba. Mu ifu ya putty, mugihe cyose gufata amazi ari byiza kandi ibishishwa bikaba bike (70.000-80,000), birashoboka. Birumvikana ko hejuru yubukonje, niko gufata amazi ugereranije. Iyo ubwiza burenze 100.000, ubwiza buzagira ingaruka kumazi. Ntabwo ari byinshi.
7. Ni ibihe bimenyetso by'ingenzi bya tekinike ya hydroxypropyl methylcellulose (HPMC)?
Hydroxypropyl ibirimo hamwe nubwiza, abakoresha benshi bahangayikishijwe nibi bipimo byombi. Abafite hydroxypropyl nyinshi muri rusange bafite amazi meza. Iyifite ubukonje bwinshi ifite amazi meza, ugereranije (ntabwo rwose), naho iyifite ubukana bwinshi ikoreshwa neza muri sima ya sima.
8. Nibihe bikoresho nyamukuru byahydroxypropyl methylcellulose (HPMC)?
Ibikoresho nyamukuru bya hydroxypropyl methylcellulose (HPMC): ipamba itunganijwe, chloride methyl, okiside ya propylene, nibindi bikoresho fatizo, soda ya caustic, aside, toluene, isopropanol, nibindi.
9. Ni ubuhe butumwa nyamukuru bwo gukoresha HPMC mu ifu yuzuye, kandi bibaho muburyo bwa shimi?
Mu ifu yuzuye, HPMC ifite uruhare runini rwo kubyimba, gufata amazi no kubaka. Kubyimba: Cellulose irashobora kubyimba kugirango ihagarike kandi igumane igisubizo kimwe hejuru no hepfo, kandi irwanya kugabanuka. Kubika amazi: kora ifu ya putty yumye gahoro gahoro, kandi ufashe calcium yivu gukora mugihe cyamazi. Ubwubatsi: Cellulose ifite amavuta yo gusiga, ashobora gutuma ifu ya putty yubaka neza. HPMC ntabwo yitabira imiti iyo ari yo yose, ariko igira uruhare gusa. Kongeramo amazi kumashanyarazi no kuyashyira kurukuta ni reaction ya chimique, kuko havutse ibintu bishya. Niba ukuyemo ifu ya putty kurukuta kurukuta, ukayisya ifu, ukongera ukayikoresha, ntabwo izakora kuko havutse ibintu bishya (calcium karubone). Ibice byingenzi bigize ifu ya calcium yivu ni: imvange ya Ca (OH) 2, Ca O hamwe na CaCO3, CaO + H2O = Ca (OH) 2 - Ca (OH) 2 + CO2 = CaCO3 ↓ + H2O Kalisiyumu yivu iri mumazi no mwuka Mubikorwa bya CO2, karubone ya calcium ikora, mugihe HPMC igumana amazi gusa, ikagira uruhare muburyo bwiza bwa calcium.
10. HPMC ni selile ya ionic selile, none non-ionic niki?
Mu magambo y’abalayiki, abatari ion ni ibintu bidatera ioni mu mazi. Ionisation bivuga inzira electrolyte igabanyijemo ion zishishwa zishobora kugenda mubwisanzure mumashanyarazi yihariye (nk'amazi, inzoga). Kurugero, sodium chloride (NaCl), umunyu turya burimunsi, ushonga mumazi na ionize kugirango ubyare sodium yimuka yimuka kubuntu (Na +) byuzuye neza na ioni ya chloride (Cl) byashizwemo nabi. Ni ukuvuga, igiheHPMCishyirwa mumazi, ntabwo izitandukanya na ion zashizwemo, ariko ibaho muburyo bwa molekile.
